Development of a low-cost insulin infusion pump software simulator: a case study with a Brazilian company

The purpose of this paper is to describe the development of a low-cost insulin infusion pump software simulator. The simulator was built using Java programming language and replicates the interface and functions of a real low-cost insulin infusion pump currently under development. Potential users participated in a remote session, and assessment was conducted using a standard usability scale (SUS). With a sample size of 34 participants possessing different levels of knowledge regarding diabetes and infusion pumps, the mean SUS score obtained was 67.43. While the insulin infusion pump is a specialised device and its system may not be immediately familiar to all users, the results suggest that usability can improve with appropriate training and clinical support. Employing a simulation model during the development of the physical prototype may provide advantages for system design, safety, and effectiveness in health care technology delivery.
